Latest Patents

One of Panuski's latest innovations is the **All-optical spatial light modulator**. This invention features a spatial light modulator (SLM) made up of a two-dimensional array of optically controlled semiconductor nanocavities. This design allows for fast modulation rates, small pixel pitches, low pixel tuning energies, and the capacity for millions of pixels. The device utilizes incoherent pump light from a control projector, which tunes each photonic crystal cavity through the free-carrier dispersion effect, thereby modulating the coherent probe field emitted from the cavity array. The high-Q/V semiconductor cavities included in the design facilitate energy-efficient all-optical control, eliminating the reliance on individual tuning elements that could potentially degrade performance or increase the size of the optical surface. Through this technology, an SLM capable of 10 pixels with micron-order pixel pitch and GHz-order refresh rates can be achieved, utilizing less than 1 W of pump power.

Another significant patent is the **Microcavity-enhanced optical bolometer**. This invention leverages optical microcavity resonance measurements, achieving readout noise that matches the fundamental limits imposed by thermal fluctuations within the cavity. The design incorporates small-heat-capacity, wavelength-scale microcavities serving as bolometers, overcoming the limitations faced by existing bolometer technologies. These microcavities can be realized as photonic crystal cavities or micro-disks, thermally coupled to efficient mid-infrared or long-wavelength infrared absorbers, such as pyrolytic carbon columns. The innovative structure features microcavities and absorbers resting on hollow pillars that extend from a substrate, allowing thermal isolation from the rest of the bolometer. This design ensures that thermal transfer to the absorbers primarily occurs through radiation rather than conduction. As the absorbers capture thermal radiation, they cause a shift in the resonance wavelength of the cavity, which is then transduced into an optical signal through the variation in reflection or scattering of near-infrared probe light.
